MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error  Code  214  -  Tophandler  Forklift  Sensor Indication Failure - Continued 6. Check    continuity    between junction box X182 pin 2 and junction box X183 pin 7 and between  junction  box  X182 pin 3 and junction box X183 pin 8. If   continuity   is   not   present, repair   or   replace   cable   from junction  box  X183  to  junction box X182 (WP 0111 00). 7. Disconnect  connector  X181 from tophandler junction box located at end of boom. Check voltage between junction box pin   A  and   pin  B.  Voltage should be 20-25V. a. If voltage is not as specified, repair  cable  from  connector X181  to  junction  box  X182 (WP 0111 00). b. If   wiring   harness   must   be replaced, notify DS Maintenance. 8. Check    continuity    between junction box X182 pin 2 and connector  X181  pin  M  and between  junction  box  X182 pin 3 and connector X181 pin N. a. If  continuity  is  not  present, repair  or  replace  cable  from connector  X181  to  junction box X182 (WP 0111 00). b. If   wiring   harness   must   be replaced, notify DS Maintenance. Table 4. Error Code 243 - Tophandler Twistlock Locking Circuit Failure Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 243 - Tophandler Twistlock Locking Circuit Failure 1. Check wires and cables from tophandler  control  valve  to boom for obvious damage. Repair or replace damaged wires (WP 0111 00). 2. Disconnect electrical connector 6040 from tophandler  twistlock  locking solenoid. Place ignition switch  to  ON  position  and perform voltage check at pins 1 and 2. If 20-25V is present at connector 6040, replace twistlock locking solenoid (WP 0169 00).
